Overview:

This article will explore the VIRTUAL view of AVX Architect and look at the High-pass and Low-pass filter objects.

Description:

These filters are found in the Virtual view, under the Crossovers/Filters section of the audio processing objects.

These filters are used to remove frequencies above or below a user specified point. The High-pass filter will remove frequencies below this point, allowing frequencies above to pass. For example this would be useful for 70v speaker systems to protect the amplifier from low frequencies.

The Low-pass filter will remove frequencies above the specified point, allowing frequencies below to pass. This could be useful for removing noise above the useful range of a speaker or creating feeds for sub-bass drivers.

The factory panels for these filters are almost identical with similar controls.

The ENABLE button will disable the filter processing, acting as a bypass.

Filter type will allow you to select the filter shape and cut-off slope.

Frequency control adjusts the filter's cutoff frequency point where frequencies will start to be removed.

High-pass removes frequencies below the cutoff frequency, while Low-pass removes frequencies below the cutoff frequency.

At the top of the Factory panel is the object name, lock button, and selection mode switch.

On the right, the “Properties" window has naming, workspace location, and DSP allocation options.

• Name – The name that will appear above the object in the Virtual view and ​parameter lists and paths in UI Design view.
• Workspace Location – The location on the workspace grid where the object is.
• DSP Allocation – Which DSP in the Project is the Object in.

The “Options" section contains the channel count of the object block, and filters can contain up to the common 512 maximum channel count.

The Max Slope will allow you to select between 24d B and 48d B per octave. The default is 24d B, and selecting 48d B will allow you to access more aggressive slopes from 30d B to 48d B.​
